| Abstract: | Selective
pre-mordanting (single and double) and natural dyeing of 6% H2O2
(50%) bleached jute fabric have been carried out using myrobolan (harda) and
metallic salts (patash alum and aluminium sulphate) as mordants and aqueous
extract of tesu (palash flower petals) as dyeing agent under varying dyeing
condition to optimize the dyeing process variables. It is found that the 20 %
myrobolan followed by 20 % aluminium sulphate in sequence is a most potential
double pre-mordanting system rather than using them as single mordant
separately, considering the results of important textile-related properties and
colour yield. Effects of dyeing process variables (time, temperature, pH, MLR, mordant conc., dye conc., and
salt conc.) on surface colour strength have been evaluated to optimize dyeing
conditions. Colour fastness to washing, rubbing and light, in general, and
dyeing pH sensitivity, in particular,
for selective fibre-mordants-dye systems have also been assessed and it is
found that dyeing at pH 11 for the
system offers overall good colour yield and colour fastness properties.
Improvement in wash and light fastness is also achieved with suitable chemical
post-treatment. |
